I do certainly agree with you that having only a couple majors a year isn't enough of a sample size for variance to even out. But by the same token, a virtual major championship is far less prestigious than their real life counterpart. In real life it is definitely possible to lose a major championship (especially the Open) due to your tee time draw and the corresponding wind set you receive as a result of it.
In real golf that's different for various reasons. First of all, there are rotations between fairways. See for example Royal Saint Georges

This helps to even out the wind orientation. You cannot get headwinds or tailwinds everywhere.
Secondly, you are obliged to play with wind, you cannot play indoor.
Let me take the following example to make this last point clear.
When you play on WGT with high winds on RSG for example, you have the normal (legend) tee distance. If you get 30 mph tailwind, the tee distance is like being shorter (by roughly 50yds, the precise value is not important). If you get 30 mph headwinds, the tee distance is like being longer (by also roughly 50 yds).
Now imagine the following situation in real golf. Take a course where you don't have much wind in general and you add two additional tees. You have the normal tee, another tee 50 yds shorter and a last one 50 yds longer. Now before to tee off each single hole, each player pick up randomly a number. if you get the number 1, you drive from the short tee, if you get 2 you drive from the normal tee and if you get 3 you drive from the long tee. This is pretty much our situation when playing at WGT with high winds. Do you think professional players would accept to play under such conditions? I seriously doubt. They say nothing against the wind because you cannot do anything against that, but they would probably refuse to play under the conditions I just described.
